3.6.5 Limits Associated with Database Objects in MySQL Cluster

Some database objects such as tables and indexes have different
limitations when using the
NDBCLUSTER storage engine:

Database and table names.
When using the NDB storage engine, the
maximum allowed length both for database names and for
table names is 63 characters.

Table names containing special characters. NDB tables whose names
contain characters other than letters, numbers, dashes,
and underscores and which are created on one SQL node were
not always discovered correctly by other SQL nodes. (Bug
#31470)
